Abstract: Author-created digital agents and content corpora for electronic documents are described. A content corpora service can include application programming interfaces such as for adding content to a corpus, attaching a corpus to a document, retrieving corpora associated with an author, and searching content of a corpus. An author-created digital agent can receive a request from a consumer of a document, determine corpora associated with the document, formulate a query based on the request, and search content associated with the corpora associated with the document.

Abstract: Data is migrated between a source database and a target database. The source database management system (“DBMS”) remains operational during the migration. A user selects the source DBMS and target DBMS, provides connection information used to connect to the database management systems and selects a virtual machine instance to perform the migration in conjunction with a database migration service. After the setup is complete, the virtual machine instance in conjunction with the database migration service performs data type transformations, and other operations, without user intervention. The database migration service also converts, without user intervention, the source schema and code to a format compatible with the target DBMS. Any code that is not converted is marked to assist the user of the database migration service identify where manual re-coding is required. The database migration service can also provide recommendations as to a target DBMS that is a suitable target DBMS.

Abstract: A processing device receives a query comprising a first field value and a time period and performs a first search of a data store using the first field value to identify a plurality of events having the time period and a field that comprises the first field value. The processing device determines a first subset of the plurality of events associated with a first context definition and determines a plurality of fields specified in the first context definition. The processing device determines, for events in the first subset, field values of one or more fields specified in the first context definition. The processing device generates a report based on the field values of the one or more fields specified in the first context definition from the events in the first subset. The processing device generates a response to the query that comprises at least a portion of the report.

Abstract: Described are techniques for modifying or creating classification data used to automatically classify items in an online marketplace or catalog, based on user interaction data. For one or more classification labels that may be applied to an item, user interaction data indicative of a count of instances that the label was accessed, a length of time during which the label was accessed, counts of instances that parent and child labels were accessed, and counts of instances that the label was accessed via a search query may be determined. Based on the user interaction data, an importance score for the label may be determined. Labels having an importance score greater than or equal to a threshold value may be included in classification data and used for subsequent classification of items. Labels having an importance score less than a threshold may be excluded from the classification data.

Abstract: A technique is described herein for using personal digital assistant (PDA) functionality to assist a user in retrieving a content item from a source component, such as a remote user computing device. In one manner of operation, the technique involves: receiving at least one input message from the user, in which the user expresses an intent to obtain a desired content item; interpreting the input message(s) using a language understanding component of a dialog system, to provide an interpreted request; identifying zero, one or more source components, each of which provides a copy of the desired content item; retrieving the desired content item from at least one identified source component; and sending the desired content item over a computer network to a target component. The identifying operation involves identifying the source component(s) with reference to a hierarchically-arranged set of retrieval options.

Abstract: A first apparatus includes a memory configured to store first connection information in association with each of connections established between the first apparatus and a second apparatus. The first apparatus synchronizes the first connection information stored in the memory with second connection information that is managed by the second apparatus. When a connection is to be established between the first apparatus and the second apparatus while synchronization of the first connection information performed by the processor is suspended, the first apparatus generates first unique information that is unique at least between the first apparatus and the second apparatus, and transmits the generated first unique information to the second apparatus, and establishes, based on the first unique information, a connection between the first apparatus and the second apparatus.

Abstract: A hosted analytics system may be integrated with transactional data systems and additional data sources such real-time systems and log files. A data processing pipeline may transform data on arrival for incorporation into an n-dimensional cube. Correlation between patterns of events in transactional data may be identified. Upon arrival, new data may be transformed and incorporated into the n-dimensional cube. Similarity between the new data and a previously identified correlation may be determined and flagged.

Abstract: Reduced resolution location determination for improved anonymity of a user location is disclosed. In some implementations, a first location of a computing device operating in a geographic area is determined. A population density of the geographic area is estimated. A grid overlay is generated, including a number of cells based on the estimated population density. Using the grid overlay, a second location is generated for the computing device that is less precise than the first location. The less precise second location can be used in a local search or other application to improve the anonymity of the user location.

Abstract: Techniques are described herein for allowing a container DBMS to impose restrictions, on a per-pluggable-database basis, on operations based on the pluggable database to which the users that request the operations belong. In one embodiment, lockdown profiles can be created and mapped to pluggable databases. Lockdown profiles specify PDB-wide restrictions on operations. The restrictions may apply to all operations of a given type, may apply to specific features, may require use of specific parameter values, etc. All users that belong to a pluggable database are restricted by the restrictions specified in the lockdown profile to which their pluggable database is mapped, unless the lockdown profile has a user-specific exemption for them. Bitmaps and/or hash tables may be used to more quickly determine, at query runtime, whether a query violates any profile-specified restrictions. Execution of queries that violate any profile-specified restrictions is prevented.

The invention further provides related systems and processor-executable instructions.

Abstract: A replicated storage system allocates tables to storage clusters to balance the usage of resources in the replicated storage system. The replicated storage system determines the query load of the stored tables and generates candidate table allocations based on the query loads. The candidate table allocations are generated based on table allocation criteria based on the popularity of the tables or whether the tables are related to other tables. The replicated storage system determines resource parameters for each candidate table allocation and generates a resource usage score for each candidate table allocation based on a utility function that is weighted based on priorities of the resources used by the replicated storage system. The replicated storage system selects a table allocation from the candidate table allocations based on the resource usage scores of the candidate table allocations and allocates table replicas to the storage clusters.

Abstract: A reservation for two or more continuous time frames can be easily made. An information processing apparatus searches for two or more time continuous frames that can be reserved according to a user's request. In addition, the information processing apparatus searches for two or more continuous time frames including at least one reserved time frame in response to a request from the user and having a possibility of being able to be reserved as another user who has reserved the reserved time frames accepts movement of the reserved time frames. Then, a result of a search for two or more continuous time frames that can be reserved and a result of a search for two or more continuous time frames that include a reserved time frame and have a possibility of being able to be reserved are presented in modes distinguishable from each other.

Abstract: Methods for style modification of images in search results are provided. In one aspect, a method includes receiving user input identifying a search query from a client device, in which the search query indicates one or more predetermined search terms. The subject system determines a first collection of images that correspond to the one or more predetermined search terms and a second collection of images that exclude images that correspond to the one or more predetermined search terms. The subject system modifies images of the second collection to apply a keyword style that corresponds to the one or more predetermined search terms, and provides a listing of images to the client device. The listing of images includes both the first collection of images and the images of the second collection that are modified with the applied keyword style. Systems and machine-readable media are also provided.

Abstract: Systems and methods are disclosed for improving search results returned to a user from one or more domains, utilizing query features learned locally on the user's device. One or more domains can inform a computing device of one or more features related to a search query upon which to the computing device can apply local learning. A local search system can include a local database, a local search history and feedback history database, and a local learning system to identify features about query terms. The features can be learned from the user's interaction with both local search results and remote search results, without sending the user interaction information or other user identification information to a remote search engine. A locally learned feature can be used to extend a query, bias a query term, or filter query results.

Abstract: A data discovery service provides methods of indexing and archiving data from streaming data sources. The data discovery service can subscribe to a streaming service which transmits data collected by a streaming data source. The streaming data source may be associated with an index policy that identifies the types of data from the data stream are to be indexed, and an archive policy that identifies under what conditions an index should be archived. An index of the data stream may be generated based on the index policy until an archive event is detected. When the archive event is detected, the index can be transmitted to an archive data store and a new index can be generated for the data stream.

Abstract: Co-clustering based on generalized conceptual relationships can automatically detect story forms incorporating archetypes/targets and actions. Co-clustering can help in identifying similarities that exist in low-dimensional sub-spaces of sparse data such as textual paragraphs. Through co-clustering, the clusters themselves and their characteristic features are identifiable which can be useful in describing and summarizing their contents. The residual error of factorization with concept-based features is significantly lower than the error with prior keyword-based features. Qualitative evaluations also suggest that concept-based features yield more coherent, distinctive and interesting story forms compared to those produced by using prior keyword-based features.
